3 Claims. (01. 51 ,190)

The present invention relates to a buffing wheel'which, while not necessarily restricted to such use, is particularly designed and adapted for the purpose of cleaning; eggs of surface stains, dirt or other foreign matter which adheres to the shell and which is not readily dislodged by washing. 7

The invention broadly comprehends a driven rotary wheel and means carried by and secured to the periphery thereof in such a manner as to present a traveling continuous abrasive surface with which the eggs or other articles are contacted to free the same of surface stains,- dirt or other foreign matter adhering to the shells, and in which said means is so constructed and arranged as to permit of the accomplishment of the intended purpose with facility and dispatch, and this without incurring the risk of cracking, breakage or other damage to the article being treated.

More particularly, the invention resides in a device of the indicated character, in which the yieldable resilient means carried by and secured to the wheel periphery is in the form of a plu rality of contiguous outwardly bowed portions presenting convex abrasive surfaceaand which bowed portions in the preferred form of the invention are arranged in a plurality of circumferentially extending rows and in staggered relation to each other. I a I The invention further embodies peripheral means in the form of continuous strips of material which are of greater length than the pe-' riphery of the wheel and which are secured at circumferentially spaced points to present a suc- 'cession of outwardly bowed contiguous portions, the outer convex surfaces of which are of an abrasive character.

Another feature of the invention resides in the provision of devices for detachably securing the peripheral means or strips to the wheel periphery, whereby said means or strips may be readily removed, discarded and replaced when they are i worn.

The invention further comprehends a device of the character set forth which is comparatively simple and not complicated in its structure, which may be inexpensively produced and i maintained in working condition and which is highly efficient for its intended purpose.

With the above recited and other objects in view, reference is had to the following description and accompanying drawing, in-which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawing: Figure 1 is 'a side view of a cleaning wheel con-' structed in accordance with the invention. Figure 2 is a plan'view thereof withparts broken away and shown in section to disclose the underlying structure. Figure 3 is a'detail perspective view'of one of the securing devices. 1

Referring to the drawing by characters of reference, 5 designates the wheel body, which is preferably of wood, although it may be constructed of any other material which is suitable for the purpose. The wheel body is of circular formation and is secured to aconcentric shaft or spindle 6 which is rotated or driven in any suitable manner. Asshown, the wheel has secured thereto a hub 7, the flange 8 of which has extending therethrough and anchored in the wheel body screws or other equivalent fastening devices 9, a set screw 10 being provided for looking the hub to the shaft 6. A peripheral cleaning means is provided which is carried'by' and secured to the wheel and which in accordance with the invention consists of one ormore sets of outwardly bowed or arched elements 11 arranged in'suceession and substantially contiguous toeacho'ther around thecircumference of the periphery of the wheel, with the outer convex surfaces 12 of an abrasive nature. The elements are of a yieldable resilient character and present when the wheel is in motion, a'traveling substantially continuous abrasive surface with which eggs or equivalent articles are adapted to be contacted so as to free the same" of surface stains, dirt or matter adhering to the shells to permit of the cleaning thereof with the greatest facility and dispatch, and this without incurring the risk of cracking, breaking or otherwise damaging the articles whichare being cleaned or treated. As particularly illustrated, the elements 11 constitute portions of a continuous strip of material, two of said strips being illustrated in the present disclosure and designated generally by the reference characters A and B. The strips A and B are each of a greater length than the peripheral measurement or circumference of the wheel body 5. and said strips are secured at circumferentially spaced points to present a succession of outwardly bowed or arched contiguous portions 11. It should also be observed that the arched or bowed portions 11 of the strip A are disposed in staggered relation to said portions of the strip B.

In practice, the strips are preferably detachably secured to the periphery of the wheel body 5 so as to admit of the ready removal and replacement of the strips when worn. The detachable means of securing may assume varying forms but for the purpose of illustration, the form selected consists of a plurality of anchoring devices 15 which are cut, bent and formed from a length of resilient material to provide a flat shank or body portion 16 having instruok spurs or teeth 17 and having an aperture 18 adjacent one end thereof. The opposite end 19 is in the form of an inwardly directed spring clip. The apertured end 18 is swingably anchored to the periphery of the wheel body 5 by a staple 20, and the Wheel body adjacent its periphery is formed with an annular rim 21, the outer periphery of which rim is disposed flush with the periphery of the wheel body and constitutes a part of the bearing surface against which the secured portions of the strip bear. As shown in the present instance, two of the rims 21 are employed, one being disposed on each side face of the wheel body. It will also be ob served that the swingably anchored ends of the securing devices 16 for the strip A are disposed together with the staples 20 within the confines of the outwardly bowed or arched portions 11 of the strip B, while the devices 16 for the strip B are located within the confines of the outwardly bowed or looped portions 11 of the strip A so as to be in a non-interfering position. In applying the strips A and B, the terminals or ends 19 of the securing devices 16 are disengaged from the rims 21 and after a portion of the strip is placed against the outer bearing surfaces of the wheel body and rim peripheries, the devices 16 are swung to a position transversely across the strip and the terminals 19 sprung into embracing engagement with the rims. This forces the spurs or teeth 17 through the strips and thence into the peripheral bearing surface of the wheel body, insuring a securely clamped arrangement of the strips while permitting of their ready intentional removal when desired.

Obviously, when the wheel is rotated, the eggs or other frangible articles of this nature may be contacted with the outer abrasive surfaces 12 of the portions 11 for the purpose of cleaning and freeing the shells of foreign matter which adheres thereto.

While there has been illustrated and described a preferred embodiment of the invention, it is to be understood that variations and departures therefrom which fall within the scope of the appended claims may be resorted to when desired.

What is claimed is:

1. A device of the character set forth including a driven rotary wheel body and yieldable resilient means having an outer abrasive surface carried by and secured to the outer periphery of said wheel body, said means consisting of a continuous strip of material of greater length than the periphery of the wheel and having an outer abrasive surface and means securing said strip to the periphery of the wheel at circumferentially spaced points to present a succession of outwardly bowed contiguous portions.

2. A device of the character set forth including a driven rotary wheel body and yieldable resilient means having an outer abrasive surface carried by and secured to the outer periphery of said wheel body, said means consisting of a continuous strip of material of greater length than the periphery of the wheel and having an outer abrasive surface and means securing said strip to the periphery of the wheel at circumferentially spaced points to present a succession of outwardly bowed contiguous portions, said means consisting of securing devices swingably anchored at one end of the wheel periphery and interengaging means formed at the opposite end of said devices and on the wheel body for detachably holding said devices transversely across the strip.

3. A device of the character set forth including a driven rotary wheel body and yieldable resilient means having an outer abrasive surface carried by and secured to the outer periphery of said wheel body, said means consisting of a continuous strip of material of greater length than the periphery of the wheel and having an outer abrasive surface and means securing said strip to the periphery of the wheel at circumferentially spaced points to present a succession of outwardly bowed contiguous portions, said means consisting of securing devices swingably anchored at one end of the wheel periphery and interengaging means formed at the opposite end of said devices and on the wheel body for detachably holding said. devices transversely across the strip and means on said devices to penetrate the strip and engage in the periphery of the wheel body.
